如何从c#中删除IIS对象？

Question

作为卸载方法的一部分,我需要从.NET中删除虚拟目录和应用程序池.我在网上找到了以下代码:

    private static void DeleteTree(string metabasePath)
    {
        // metabasePath is of the form "IIS://<servername>/<path>"
        // for example "IIS://localhost/W3SVC/1/Root/MyVDir" 
        // or "IIS://localhost/W3SVC/AppPools/MyAppPool"
        Console.WriteLine("Deleting {0}:", metabasePath);

        try
        {
            DirectoryEntry tree = new DirectoryEntry(metabasePath);
            tree.DeleteTree();
            tree.CommitChanges();
            Console.WriteLine("Done.");
        }
        catch (DirectoryNotFoundException)
        {
            Console.WriteLine("Not found.");
        }
    }

但它似乎抛出一个COMException上tree.CommitChanges();.我需要这条线吗？这是一种正确的方法吗？

如果要删除应用程序池,虚拟目录或IIS应用程序等对象,则需要执行以下操作:

string appPoolPath = "IIS://Localhost/W3SVC/AppPools/MyAppPool";
using(DirectoryEntry appPool = new DirectoryEntry(appPoolPath))
{
    using(DirectoryEntry appPools = 
               new DirectoryEntry(@"IIS://Localhost/W3SVC/AppPools"))
    {
        appPools.Children.Remove(appPool);
        appPools.CommitChanges();
    }
}

您DirectoryEntry为要删除的项目创建一个对象,然后DirectoryEntry为其父项创建一个对象.然后告诉父级删除该对象.

你也可以这样做:

string appPoolPath = "IIS://Localhost/W3SVC/AppPools/MyAppPool";
using(DirectoryEntry appPool = new DirectoryEntry(appPoolPath))
{
    using(DirectoryEntry parent = appPool.Parent)
    {
        parent.Children.Remove(appPool);
        parent.CommitChanges();
    }
}

根据手头的任务,我会使用任何一种方法.
